Poison Ivy Rash on Wrist

The oil from the plant leaves irritates the skin.

The redness and blistering from the rash is often arranged in streaks or lines, because the leaf brushes across the body in a line as a person walks past.

Poison oak can grow on a tree or a vine. The leaves look wavy and grow in groups of threes.
